Description
Technical field
The utility model relates to a kind of elevator, particularly a kind of elevator that does not have machine room.
Background technology
In the prior art, a kind of machine-roomless lift is arranged, its structure mainly includes car, towing machine, counterweight frame and steel rope; Said steel rope two ends are respectively equipped with rope hitch plate; Rope hitch plate elasticity is connected on the crossbeam at elevator top, and towing machine and control housing are installed on the concrete wall surface of hoistway top or hoistway bottom, and towing machine is provided with traction sheave; Counterweight frame is provided with track adjusting wheel; Said car two bottom sides is arranged with first diversion sheave and second diversion sheave, and said steel rope is walked around track adjusting wheel, traction sheave, first diversion sheave and second diversion sheave successively, and counterweight frame and car are suspended in the elevator; Control housing is arranged on the side of car, thereby this device need not to be provided with machine room.Its weak point is: it installs inconvenient, needs to carry out towing machine at top of building and installs, and need lift the top to elevator by the towing machine that weight is bigger during installation, time-consuming, effort; Cost is higher, and communication is to be connected through the retinue ribbon cable to existing car with control housing, and the construction of cable is huge, and erected cost is high; Existing towing machine installation is had relatively high expectations to hoistway, need do a large amount of burying work beforehands simultaneously, and towing machine is installed in hoistway top layer or bottom, needs to strengthen the height or the degree of depth of top layer or bottom, and the laid down cost of elevator is higher; In addition, existing elevator maintenance difficulty, and be not easy to save oneself.
The utility model content
To above-mentioned technical matters, the utility model proposes a kind of technical scheme of machine-roomless lift, makes that the elevator construction cost is low, control is convenient.
The technical scheme of the utility model is following: a kind of machine-roomless lift, comprise car, towing machine, counterweight frame and flexible traction part, and said car and counterweight frame are suspended in the hoistway; Towing machine is provided with the traction sheave that links to each other with driver train, and counterweight frame is provided with track adjusting wheel, and said car bottom is provided with diversion sheave at the bottom of at least one sedan-chair; Said towing machine is fixedly mounted on the car bottom; Well headroom also is provided with the top diversion sheave, and flexible traction part one end is connected well headroom, and the other end is upwards walked around the top diversion sheave after walking around track adjusting wheel again; Walk around traction sheave to lower edge car one side then, walk around again at the bottom of the sedan-chair and upwards be connected well headroom along the car opposite side behind the diversion sheave; The cornerite of said flexible traction part on traction sheave is greater than 90 °.
Compared with prior art, the beneficial effect of the utility model is: one of which, elevator is easy for installation, can carry out towing machine at architecture bottom layer and install, and has reduced that towing machine is lifted the shortcoming to top layer, installs safer.Its two, need not strengthen the height or the degree of depth of hoistway top layer or bottom, saved laid down cost.Its three because towing machine need not to be fixed in the hoistway, the built-in fitting in the hoistway is few, the hoistway construction is more convenient.
For guaranteeing to have enough big friction force between flexible traction part and the traction sheave; Avoid skidding; Diversion sheave can be provided with two at the bottom of the sedan-chair, and flexible traction part is walked around behind the traction sheave at the bottom of the sedan-chair diversion sheave top and walked around, and upwards is connected well headroom again after the diversion sheave bottom is walked around at the bottom of another sedan-chair again.This structure makes that the cornerite of flexible traction part on traction sheave is bigger, can bear bigger friction force; The size of traction sheave also can be done forr a short time.
For ease of control housing is overhauled, the said control housing that is used to control the elevator operation is installed in car one side.During maintenance, can car be placed the hoistway bottom, when control housing is overhauled, need not to ascend a height, in the daily management, also can in car, overhaul control housing through passage.Communication is to be connected through ribbon cable to the car of traditional elevator with control housing, and in the utility model, the lift car communication cable links to each other with control housing nearby, has saved a large amount of control paths.
Said flexible traction part can be a steel rope, can also be the polyurethane composite steel band.When especially adopting the polyester composite steel band, since big with the traction sheave contact surface, bigger friction coefficient had between the two, can do traction sheave very little, alleviated weight, practiced thrift material.
For can reduce elevator operation and stop between the impact that causing, said flexible traction part elasticity is connected well headroom.
For making things convenient for the personnel in the car to save oneself, said car is provided with the spanner that declutches of manual control towing machine.In the prior art; Also be provided with the palm that declutches on the towing machine, therefore run into emergency situation, during like outage; Can utilize the weight difference of car and counterweight that elevator is parked in flat bed nearby; But, can only just can operate the interior personnel of the elevator operation of can't saving oneself because towing machine and car are separated through other people operation.The improvement of present technique scheme makes that the personnel in the elevator can oneself operate, and elevator is parked in flat bed nearby, and elevator uses safer.
